IMPROVEMENT IN MACHINES FOR HEELING BOOTS AND GAITERS.

Specification forming part of Letters Patent No. 145,645, dated December 16, 1873; application filed November 13, 1873.

To all whom it may concern:

Be it known that I, LEOPOLD GRAF, of Newark, in the county of Essex and State of New Jersey, have invented a new and useful Improvement in Machines for Heeling Boots and Gaiters; and I do hereby declare the same to be afull, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification, in which drawing Figure 1 represents a sectional side View of a heeling machine with my improvement. Fig. 2 is a detached sectional view of my invention in a larger scale than the previous figure.

Similar letters indicate corresponding parts.

This invention consists in the arrangement of a tubular receiver on the last of a machine for boots and shoes, so that if said machine is used for putting heels on boots or gaiters, the edges or ends of the legs of said boots or gaiters are prevented from catching between the last and the anvil, and the work of heeling boots or gaiters can be performed success fully on the same machine which is used for heeling shoes.

In the drawing, the letter A designates the last of a heeling-machine of that class known by shoe manufacturers as McKays heelingmachines. On the upper edge of this last is secured a tubular receiver, B, which projects upward, andis made large enough to admit the anvil O. From this anvil extend pins to av into sockets b b, made in the last for the purpose of guiding said last in its up-and-down movements.

In order to secure a heel in position, the boot or gaiter to which the same is to be attached is put on the last A, the leg of said boot or gaiter extending over the tubular receiver B, as shown in the drawing. The heel is adjusted on the plunger D, and by forcing the plunger up the tacks are driven through the heel and through the sole of the boot or gaiter, and by coming in contact with theiron. sole of the last said tacks are clinched; but in raising the plunger the last is forced up against the anvil O, and if the tubular receiver B is not applied the upper edge of the leg of the boot or gaiter-is liable to catch between the upper end of the last and the anvil, and the work is damaged.

By the simple application of my tubular receiver therefore the same machine which is used for heeling shoes can also be used for heeling boots and gaiters, and considerable expense in machinery is saved.

What I claim as new, and desire to secure by Letters Patent, is-

A tubular receiver arranged on the last of a lieelingmachille, substantially as shown and described.

This specification signed by me this 10th day of November, 1873.

LEOPOLD GRAF.
